Furnace Installation FAQs

How do I know if I need a new furnace?

You may need a new furnace if your system is old, needs frequent repairs, does not heat properly, makes unusual noises, increases your energy bills, or has major component failure. A professional inspection can help determine whether repair or replacement is the better option.

How long does furnace installation take?

Most standard furnace installations can often be completed in one day, depending on the property, existing system, venting, gas connection, and installation requirements. More complex installations may take longer.

What size furnace do I need?

The right furnace size depends on property size, insulation, ductwork, ceiling height, windows, layout, and heating demand. A furnace should not be selected by square footage alone. A proper assessment is recommended.

Do you install gas furnaces?

Yes. Extel Gas installs gas furnaces for residential and commercial customers across Scarborough, Toronto, Markham, Pickering, Ajax, Whitby, Mississauga, Brampton, and nearby GTA areas.

Should I repair or replace my furnace?

If the furnace is newer and the repair is minor, repair may be suitable. If the furnace is old, inefficient, frequently breaking down, or expensive to repair, replacement may be the better long-term choice.

Do you provide furnace installation for businesses?

Yes. Extel Gas provides commercial furnace installation for offices, retail spaces, rental properties, small commercial buildings, and property-managed locations.
